Emulation
This app works with: SheepShaver, Basilisk II,

SoftwareFPU is a Control Panel that allows most 68K applications expecting a math Floating Point Unit (FPU) to work properly on Macintoshes without one, such as: Macintosh IIsi, IIvi, Macintosh LC series, Classic II, and Color Classic series, Performa series, and some models of the Quadra, PowerBook, and PowerBook Duo series. SoftwareFPU will also work on PowerPC Macintoshes. SoftwareFPU is fully compatible with Systems 6, 7, and 8, and is PowerPC native.

2nd DL: Contains "SoftwareFPU 3.07". Bug-fixed for use on Mac OS 8.5 and later. Also, has shareware nags removed (free for non-commercial use release). Stable.

The PFD manuals included with SoftwareFPU are also included as a separate 'Manuals' download above, too.

Why use SoftwareFPU?
SoftwareFPU allows you to use your FPU applications now, instead of waiting for a software upgrade or buying an FPU card. On Power Macintoshes, SoftwareFPU is the only way you can use 68k FPU applications until they are available in PowerPC-native form(¹).

(¹) Was true, until John Neil & Associates bought the rights to the code for a much faster 68K FPU emulation from Tom Pittman, and marketed it as "PowerFPU".

Compatibility
Architecture: 68k PPC

SoftwareFPU will not work on 68000 Macintosh's such as the Macintosh Plus, SE, Classic, Portable, and PowerBook 100.

Because of a 68LC040 CPU chip bug, some applications crash with SoftwareFPU on 68LC040 Macintosh.

In addition, if a developer only offers color Macintosh II and black and white Macintosh Plus/SE/Classic versions of their software, SoftwareFPU allows users to take advantage of color features in the Macintosh II version, rather than settling for the black and white Macintosh Plus/SE/Classic version.

Anyone could upload PowerFPU, the PowerPC counterpart of SoftwareFPU, please?
